Question 675865
y = 1.8x
comparing to the y=mx+b slope-intercept format
slope, m,  is 1.8
y intercept, b, is 0
...
{{{graph(300,200,-10,10,-10,10,1.8x)}}}
...
When given the slope and a point, use the point-slope formula to determine the linear equation.
...
y-y1 = m(x-x1)
...
y - 0 = -2(x--3)
y = -2(x+3)
y = -2x + -6
{{{highlight_green(y=-2x-6)}}}
...
{{{graph(300,200,-10,10,-10,10,-2x-6)}}}
